Planning a Unit in mathematics Unit: Year 4 Block B3 Securing number facts, understanding shape Lessons: 15

Learning objectives - Most children will learn to: Vocabulary Building on previous learning Children's targets 1. Identify and use patterns, relationships and Check that children can already: 1. I can start with a calculation such as 18 3 15 and use properties of numbers or shapes; investigate a problem, solution, calculator, number patterns to create a family of calculations with the statement involving numbers and test it with calculate, calculation, same answer: examples equation, operation, inverse, 180 30 150 190 40 150 answer, method, explain, 2. Solve one-step and two-step problems involving 200 50 150 numbers, money or measures, including time; predict, reason, reasoning, I can draw polygons on triangular grid paper and pick out choose and carry out appropriate calculations, pattern, relationship, rule, some of the properties they have in common using calculator methods where appropriate sequence, sort, classify, 2. I can work out how to solve problems with one or two 3. Report solutions to puzzles and problems, property steps giving explanations and reasoning orally and in I can decide what calculation to work out and whether a writing, using diagrams and symbols add, subtract, multiply, divide, calculator will help me 4. Use knowledge of rounding, number operations I can think about the numbers in a calculation and choose sum, total, difference, plus, a good way to do the calculation and inverses to estimate and check calculations minus, product, quotient, 3. I can describe how I solved a problem about shapes using 5. Use knowledge of addition and subtraction facts remainder, double, halve, mathematical vocabulary and place value to derive sums and differences factor, multiple, divisor, round 4. I can use inverse operations to help me check calculations of pairs of multiples of 10, 100 or 1000 If you give me a number fact, I can tell you some related 6. Identify the doubles of two-digit numbers; use to 3-D, three-dimensional, 2-D, facts calculate doubles of multiples of 10 and 100 two-dimensional, net, 5. Because I know number facts such as 8 - 3 5, I know that 80 - 30 50. I can use this to work out calculations such as and derive the corresponding halves construct, regular, irregular, 7. Derive and recall multiplication facts up to 10 86 - 36 50 concave, convex, symmetrical, I can find differences between numbers such as 2993 and 10, the corresponding division facts and line of symmetry, vertex, 3000 because I know facts such as 3 7 10 multiples of numbers to 10 up to the tenth vertices, face, edge, polygon, 6. I can work out doubles of two-digit numbers multiple equilateral triangle, isosceles Because I know that double 9 is 18, I know that double 900 8. Visualise 3-D objects from 2-D drawings; make triangle, quadrilateral, is 1800 nets of common solids rectangle, square, oblong, Because I know that double 80 is 160, I know that half of 9. Draw polygons and classify them by identifying hexagon, heptagon, octagon 160 is 80 their properties, including their line symmetry I know that doubling and halving are inverse operations 10. Use time, resources and group members 7. I can tell you answers to the 9 times-table, even when the questions are not in order efficiently by distributing tasks, checking If you give me a multiplication fact I can give you one or progress, making back-up plans two division facts that go with it I know what a factor of a number means. I can find all the factors of 36 8. When I look at a drawing of a 3-D shape I can work out what shapes I need to make its net, such as four triangles and a square to make a square-based pyramid 9. can pick out 2-D shapes that have more than one line of symmetry I can draw lots of different polygons on squared paper and tell you their mathematical names I can draw all the shapes made from squares placed edge to edge and tell you what sort of polygon each one is 10. I can work with a group of other children to discuss and plan how we will solve a problem Target Pupils
